New Zealand Freshwater Fish

11004-39001 Mosquito fish (Gambusia affinis) male (foreground), and female. Gambusia were released in New Zealand in the 1930s to control mosquitoes, but as with a number of other countries they soon became pests competing with our native fish. Today they are classed as an ‘unwanted organism’ under the Biosecurity Act 1993, and it is unlawful to possess or release this fish. Our own native fish do better at controlling mosquitoes *
